To all whom 'Zt 'may concern:

Be it known thatwe, EDWARD ZrnAoiI and GlonoN BRAUN, both citizens of lthe United States, and residents of Duncan, in the county of- Platte and State of Nebraska, have invented a new and. Improved Power- Transmission Attachment for Automobiles of which the following is a full, clear, and exact description. n

Our invention relates to power transmission attachments for automobiles, by which the engine of the automobile may be used to do a variety of w'ork. As our attachment is constructed, it is adapted4 to support the rear axle of the automobile, with the wheels mounted on the said axle raised from the ground, and tohold in frictional contact with the said wheels of the automobile, driving wheels, the driving wheels being keyed to a shaft on which is mounted a pulley which maybe connected by means of a belt with the machinery which is to be driven.

Still other objects of the invention will appeal' in tion.

In this specification we will describe the .preferred form of our invention, it being understood that the scope of the invention is defined in the appended claims.

Reference is to be had to the accompanying drawings forming a part of thisspeciiication, in which similar characters of reference indicate corresponding parts in allthe views, and in which- Figure l is a side elevation of our attach'- n'icnt shown as applied to an automobile; Fig. 2 is an end viev' of' Fig. 1; Fig. 3 is a sectional View on the line 3-3 of Fig. ll; and Fig. fl is a sectional View on the line ll-a of Fig. 3.

By referring to the drawings it will be seen that a frame is provided consisting ot bottom members 5, standards 6, which arev secured thereto, braces 7, which connect. the upper terminals of the standards with the bott-om members 5, and angular supports 8 which have one set of their terminals hinged at 9 to members 10 of the frame. The standards G carry bearingspll in which is jonrnaled a shaft 12, there being-also additional bearings 13 in which the shaft 12 is journaled, these additional bearings '13 being carried by additional standards ll which are secured to the frame. A pulley 15 is keyed to the shaft. 12 between the :uldit-ional the following complete descrip-4 standards 14. Brace members 16 are secured to the standards G at their upper terminals, these ,brace members 1G being disposed inwardly and being secured to a transverse member 17 of the traine and to the additional standards 14.

Keyed to the shaft l2 are two driving wheels 18, the driving wheels 1S being disposed beyond the standards (3 and having inner hubs 19, these inner hubs being separated from the bearings 1l by means et washers 20. W e prefer to use these washers 2O instead of collars ou the shaft 12, for by means of this arrangement it is possible more readily to remove and replace the sha ft 12 in its bearings.` The outer terminals 2l of the shaft 12 which extend beyond the driving wheels 18, are angular in shape in order that either terminal may be connected to one end of a universal joint to the other end of which a shaft. -to be driven may be secured. The peripheries of the driving wheels 18 are concave transversely in order that a better frictional engagement may be had with the wheels 22 of the automobile, but if desired, the driving wheels 1S may be constructed without the concave surfaces.

The angular supports 8, which are hinged at 9 to the frameinembers 10,have one set of .arms 23 which rest on the said frame members l0, the remainder of the supports extending upwardly and having recesses or cutaway portions 24, The supports 8 :1 -lso have ori tices 25 at each side of the cutaway portions 24, these orifices 25 extending to the said l cutaway portions. Bearing members 2G having orifices, are provided, bolts 2T being disposed through the orifices 1n the bearing members 2G, the bolts extending through said orifices 25, by which means the bearing members 2G are held in place on the supports 8. The bearing members 2G are considerably smaller 4than the cutaway portions 24 so that they may be moved upwardly and downwardly, and forwardly and rearwardly, 'so that they may be adjusted with reference to the automobile. These bearing 1nembers-26 are adapted to be disposed nnder the axle 2S ot'the automobile to supportthc said axle sutlieiently high to raise the automobile wheels 22. The orifices in the, supports S are disposed above each other, so that the bearings 2G may be held in` place relatively to'tholsupports 8 as desii-ed, and inasmuch as the bearing members lll) 26 may be moved forwardly or rearwardly on the bolts 27, the automobile ax'le 28 may be carried by tlie bearings 26 near the forward or the rear ends of the supports, as may-'be desired. Bolts 29are provided, by which the arms 23 of the supports 8 may be held firmly against the members 10 of the frame. Braces 30 are also provided, which are pivoted to the upwardly-extendin members of the supports 8, these braces 30 aving hoks 31 which engage the memberslO to assist'in holding the supports in osit-ion. The braces 16 have orifices throng which extend threaded terminals of tie members 32, the tie members 32 having hooks33 at their outerterminals, the hooks being adapted to be disposed around the axle 2,8of the automobile,enut members 34 being providedto-engage-the threaded terminals of the tie members432 beyond the braces 16, by which means the frame may be held in place with the driving wheels 18 in frictional contact with the automobile Wheels 22.

.In vusing our invention, the suplp the frame are disposed under t orts 8 of of the automobile, and the automobile may be raised 'in any suitable manner, and the bearings 26 may be disposed in place under and in engagement with the'axle 28-. This having been done, the tie members 32 are adjusted in place, by which means the driving wheels 18 will be brought and held in' contact with the automobile wheels 22. It will then be possible to start the engine and connect the pulley with the machinery which is to be driven, by means of a belt in the usual manner.. A It is, of course, understood that Babbitt metal is used in the bearing 26 and that Babbitt metal is also used in the bearings 11 and 18. As the supports 8 are hinged to the members 10, the device may be'disposed in position, but with the su ports S lowered before the rear axle'of t e automobile is raised, it being merely necessary to raise the supports 8 and adjust their bearin members 26 under the automobile axle a ter it has been raised with its .wheels o the ground. When the'automobile is 'to be freed from the attachment, the tie members 32--having been removed, the sup orts may be knocked inwardly, to free the earing members from the automobile axle without the necessity of raising the automobile axle free from the bearing'members.

Having thus 'described our invention, We claim as new and desire to secure by Letters Patent:
